摘要
通过土培试验 ,研究了微生物菌剂、富里酸和有机无机复合肥对玉米苗期根系生长的影响。结果表明 :施用微生物菌剂、富里酸和有机无机复合肥能增加玉米苗期根长 ,减小根半径 ,扩大根系体积、根系吸收表面积和根系密度 ,有利于根系对营养元素尤其是磷素的吸收。
Pot experiment was conducted to study the effects of microbial fertilizer, fulvic acids and organic mineral compound fertilizer on root growth of maize during seedling stage The results showed that root length increased, root radius decreased, volume, absorbent surface area and density of root expanded after the application of microbial fertilizer, fulvic acids and organic mineral compound fertilizer, which was beneficial to absorption of nutritional element, especially phosphorus, in root system
